BENJAMIN URICH, OF MILWAUKEE, WISCONSIN.

PUNCTURE-CLOSING DEVICE FOR TIRES.

Application filed August 31, 1921. Seria1 No. 497,405.

Be it known that I, BENJAMIN Umori, a citizen of the United States, residing in the city of Milwaukee, county of Milwaukee, and State of Idlisconsiii, have invented a certain new and useful Improvement in Plmcture-Closing Devices for Tires; and I do declare the following to be a clear, exact, and complete description thereof, such as will enable persons skilled in the art to which the invention relates to make and use the same, reference being had to the accompanying drawing `for a disclosure of one form in which the invention has been embodied.

The object of my present invention is to simplify the construction shownin my prior Patent N o. 1,313,868, granted to me on August 19, 1919, so as to enable af'more economical production of like puncture closing devices to be achieved. The device disclosed in my prior patent involves in its manufacture some very expensive operations, which are completely eliminatedv in my present invention. The operation of seating the needle in the handle of the patented construction has been most expensive and has induced me to simplify the device so as to avoid the necessity for the expensive voperations heretofore performed.

The novel features of my present invention will be pointed out in the claims appended to this specification.

In the drawings which accompany this specification,

Figure 1 is a View in side elevation of my improved puncture closing device, showing the manner of its use in connection with the repair of a punctured bicycle tire.

Fig. 2 is a plan view of the device shown in Fig. 1.

Fig. 3 is an enlarged fragmentary View in elevation opposite to that shown in Fig. 1.

Fig. 4 is a sectional view on the line 1----/1, Fig. 3, looking in the direction of the arrow.

It has long been the practice to repair punctured tires by the use of devices adapted to serve a rubber band in attenuated condition with several parallel windings, so that when the band is inserted in the puncture, and a closing cement applied thereto, the band will expand when released by the serving device, with the effect of completely and effectively closing the puncture.

In my prior patent I utilize the tension of the elastic band to hold the supporting hook in operative position so that by merely turning the hook at the proper time, the tension of the band would be relaxed.

In the present invention I make use of the same principle of operation disclosed in my former patent, but have greatly simplified the construction of the device whereby the results desired are attained.

Referring now to the drawing, the numeral 10 indicates a handle which may be economically produced by stamping or casting. The forward end of the said handle is formed with a projection l1 so as to stand at an angle to the direction of the length thereof, and is provided with a perforation 12, through which the needle 13, having a fork 14: at its free end may be passed. The rear end of the needle is formed with an eye 14 adapted to be brought into registry with a perfo-ration 15 extending transversely of the handle and properly located with reference to the length thereof. In forming the perforation 15, a boss 16 is extruded upon the side of the handle opposite to that upon which the projection 11 is formed. The end of the needle is passed through the opening 12, in the projection 11, and the eye 14 is brought into registry with the perforation 15 in the handle. A tubular rivet 16 is passed through the eye of the needle and the perforation 15, and the pointed end thereof is spread upon the boss 16 to unite the needle rmly to the handle, with the parts in close engagement as indicated in Fig. 2.

The tubular rivet forms a journal bearing for the shank 17 of the hook 18, which normally supports the band extending from the forked end of the needle. As before stated, the tension of the band retains the hook in proper position for insertion in the puncture in the tire and it is necessary in discharging the band into the puncture only to press the lever 19 of the hook with the thumb or finger, to rotate the shank 17 in its journal and free the distended band from its engagement with the hook, as in my prior patent.

The construction embodied in my present invention is extremely simple and most economical in production, it having all of the eiiciency of my former patented device and several advantages from an economical standpoint. f

It will be observed that the points of attachment of the needle to the handle are separated by a considerable distance, and

that that :partof the needle-extending between the points of attachment, lies in `'close- 1. In a puncture closing device for tires,

the ycombination of a handle and a needle, the latter being forked lat its free-end and provided with an---eye by nieans of which it is attached to thehandle, with a hook jour- .naled in the handle Yand adapted tobe 'held in operative position by an elastic band extendingfrom the fork of the needle, and

to ybe turned to disengage the elastic band from the hook.

2.In a Apuncture closing device for tires, the combination of a needle forked iat Iits free end and provided with an eye at the other, a handle having a projection atv one end zprovided With ineans for engaging the needle at an intermediate point, and means passing throughthe eye of the needle -to secure the latter to the handle, with a hook pivoted on the handle and adapted vto lbe held in Ioperative positionbyl a `distended elastic band, and to be. turned to disengage the elastic band from the hook.
